On this page I'll
quickly explain how to cut AVI files, for example DivX movies.
Main purpose for cutting a movie is to either
make it fit on a CD (removing the credits or removing the intro)
or to split a movie into two files for copying them on two CD's.
Note: Read the disclaimer!
How to cut an AVI file
For cutting a movie we will use VirtualDub.
You can download the most recent version at the VirtualDub
The current version of VirtualDub
is pretty easy to install: Unzip the archive (ZIP file) using WinRar
or WinZip to a folder.
Usually, I copy this entire folder
to C:\Program Files
and make a shortcut to VIRTUALDUB.EXE
(there is a special Pentium 4 version, this one needs to be downloaded
and added to the content of the VirtualDub
folder, the filename of the Pentium 4 version is VEEDUBP4.EXE!).
After installing VirtualDub,
you can start the application.
Example 1: Cut the credits
This first example shows you how to cut
away the end credits of a movie.
First open the AVI file using the menu
"File" - "Open video file..."
(or press CTRL+O).
A file dialog will appear. Using this dialog,
browse to the AVI file you want to make shorter, select it and open it.
will now show this window;
The basic approach here is to select the
part that we want to have. This means that the part we select will become
the content of our new AVI file.
If you want to cut only the credits, then
the first frame of the AVI will remain the first frame.
Click the "Mark In"
This will mark the beginning of this AVI file as the beginning of the
selected part of the AVI file.
In case you're not sure if the indicator
is at the beginning of the slider as shown below (red arrow points to
The next step will be determination of
the end point within the AVI, which we mark with the "Mark
Out" button ().
You can use the slider to determine the
proper position. I usually move the slider way to the right and slowly
move it to the left up until the point where I start seeing the movie
instead of credits. Then I start moving the slider to right again, using
the "Key next" button (),
which jumps to the next key-frame each time you click it. Alternatively
you could use the "Scene Forward" button ()
to let the movie play where you click the "Stop"
once you found the proper position.
Once we found the end position, we can
click the "Mark Out" button ().
You will notice on the slider bar that
a gray bar will appear between the mark-in and mark-out points. This indicates
that this is the piece that we want to keep.
Now we need to do some settings on how
copy this. Since we only want to remove the end of this move and do not
intend to change compression or anything else, we need to tell VirtualDub
to do so.
First choose from the "Video"
menu, the option "Direct Stream Copy". We do
the same for the "Audio" menu, also select
"Direct Stream Copy".
Once we have done that, we can choose from
the "File" menu, the option "Save
as AVI" or simply press F7. VirtualDub
will now start saving the selected scene, a dialog will keep you informed
on it's progress:
Once that is completed, you're done. It's
not a bad idea to test the result afterwards.
Example 2: Split a movie into two
This is commonly used when an AVI file
needs two (or more) CD's space wise.
Basically we repeat the first example,
the only difference is that for the first cut, our ending position will
be (when cutting it into two parts) the middle of the movie.
The rest will remains the same; set "Audio"
and "Video" to "Direct Stream
Copy" and use "File" - "Save
as AVI" to save the first part.
completed this, we must select the second part. This is done pretty simple,
as the slider is still positioned at the end of the previously marked
scene. Simple click the "Mark In" button ()
- and the end of the previous scene is now marked as the beginning of
the next cut.
moving the slider a little bit to the left, so there will be a little
overlap when switching CD's. Don't forget to press the "Mark
In" button ()
Now move the slider to the end of the move
and press the "Mark Out" button ()
and repeat the steps: set "Audio" and "Video"
to "Direct Stream Copy" and use "File"
- "Save as AVI" to save the second part.
Pretty easy he?
